Experimental study on mix proportion of recycled concrete with super plasticizer

In order to get the best mix proportion of recycled concrete with super plasticizer, an experimental research method of mix proportion of recycled concrete with super plasticizer is designed. The whole experimental scheme and steps are described in detail. By adding a kind of additive, i.e. super plasticizer, into recycled concrete of different strength grades (prepared with waste concrete and mixed with part of natural concrete), and testing the performance of recycled concrete in laboratory, the best mix proportion of recycled concrete with super plasticizer is obtained, which lays a foundation for realizing the best parameters of high performance of recycled concrete.
